The four factors of evolution are: mutation, gene flow, genetic drift, and natural selection. ... Genetic drift has much more effect in small populations, which may have an allele drift to fixation, in which all members have that allele.

can u explain this factors in short ?
a change in the basic (genetic) structure of a living or developing thing is known as mutation
gene flow is the transfer of genetic variation from one population to another.
variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce is known as genetic drift.
the process by which those animals and plants which are best suited to the conditions in which they live have more young and live longer is known as Natural selection.
